We study the effect of a hidden charm nuclear excited state N_cc* in the \ensuremathπ^\ensuremath-p\ensuremath→D^\ensuremath-\mathrm\ensuremathΣc+ reaction near threshold using an effective Lagrangian approach. We calculate the background contribution of the t and u channels by the D*0 vector meson exchange and \mathrm\ensuremathΣc++ intermediate state, respectively. We show that the consideration of a N_cc* resonance provides an enhancement of the total cross section close to the reaction threshold. We also evaluate the differential cross section for different energies and we study the angle dependence. It is expected that our model calculations will be tested in future experiments.
